His moves are about the same. He is much stronger. His special technique is deferent. If you jump and press special he'll spike a chidori. You can also charge his chidori(lighning blade) and he can also use sharingan. But unlike Normal Kakashi his health doesn't decrease while he is in sharingan mode. Hope that helped.

There is a rumor that Tobi is Obito. Tobi has heavy armor under his cloak. Kinda like Darth Vader. His right eye is the only one that shows. His left eye has not been shown yet. Note: Obito gave his left eye to Kakashi. Just watch this. [The proof.]http://www.youtube.com/watch?v=hI501T3Ju0Q[/link]
